Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion soft-pack battery tab flattening, in particular to a lithium ion soft-pack battery tab flattening device. Background Art

[0002] The tabs of lithium-ion soft-pack batteries are a component of soft-pack lithium-ion battery products. They are metal conductors that lead the positive and negative electrodes out of the battery cell. Generally speaking, the tabs of the positive and negative electrodes of the battery are the contact points during charging and discharging. When processing lithium-ion soft-pack batteries, the tabs need to be flat.

[0003] For example, a lithium-ion soft-pack battery tab flattening device disclosed in Chinese patent CN211578880U includes a first clamp body, a second clamp body and a fixed shaft, wherein the first clamp body is arranged on the second clamp body through the fixed shaft, a first pressing plate is arranged on the first clamp body, the first pressing plate is rotatable, and a second pressing plate is arranged on the second clamp body. The utility model has the advantages of simple structure, easy production, low cost, adjustable torque and convenient use, and more efficient pressing surface flattening.

[0004] Although this structure can level the tabs of lithium-ion soft-pack batteries, the device requires the operator to hold the tabs by hand, which affects the leveling effect of the tabs of lithium-ion soft-pack batteries. Therefore, we propose a lithium-ion soft-pack battery tab leveling device that can stably level the tabs of lithium-ion soft-pack batteries to improve the leveling effect of the tabs of lithium-ion soft-pack batteries.

[0009] Preferably, there are two extrusion blocks, which are symmetrically distributed about the center line of the base plate. The end of the extrusion block close to the base plate is arranged in an inclined surface, and the extrusion block is arranged in contact with the inclined surface of the base plate. Under its restriction, when the extrusion blocks move in opposite directions, the base plate can be squeezed and slide on the outer wall of the slide rod to make it contact with the pole ear.

[0010] Preferably, the outer wall of the opposing threaded rod is rotatably connected to the inside of the support block, and the outer wall of the extrusion block is slidably arranged with the top surface of the processing table. Under their restriction, the rotation of the opposing threaded rod can drive the extrusion block to move in opposite directions to contact and extrude the bottom plate.

[0011] Preferably, there are two clamping frames, which are symmetrically distributed about the center line of the top surface of the processing table. The outer wall of the clamping frame and the outer wall of the conveying roller are slidably arranged, and under their restriction, the clamping frame can stably clamp the battery body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The tab leveling device for lithium-ion soft-pack battery is composed of a leveling assembly as one component. When the tab fixedly mounted on the outer wall of the battery body needs to be leveled, it is clamped on the top surface of the processing table and the tab is set above the bottom plate. At this time, the top surface of the bottom plate needs to be in contact with the tab for support. At this time, the opposing threaded rods are rotated. Since the limiting blocks are slidably arranged with the inner wall of the limiting groove, under the restriction of the limiting blocks, when the opposing threaded rods rotate, the two limiting blocks can be driven to move in opposite directions, and the extrusion blocks fixedly mounted on the top surface of the limiting blocks move in opposite directions. The inclined surface of the outer wall of the extrusion block is aligned with the bottom wall. The inclined surface of the plate contacts and squeezes, so that the bottom plate slides on the outer wall of the slide rod, and the bottom plate squeezes the first spring sleeved on the outer wall of the slide rod, so that the top surface of the bottom plate contacts the outer wall of the pole ear to support the pole ear. At this time, the telescopic rod is started to push the pressure plate toward the bottom plate to level the pole ear. This structure can adjust and level pole ears of different thicknesses. When the pole ear is thicker, the opposite threaded rod is rotated to move the extrusion block in the opposite direction so that the extrusion block is no longer squeezed with the bottom plate. Under the action of the first spring elasticity, the bottom plate is pushed downward to level the pole ears of different thicknesses.

[0015] 2. The lithium-ion soft-pack battery ear leveling device is composed of a centering component as one component. When the ear fixedly installed on the outer wall of the battery body needs to be leveled, the battery body is placed on the top surface of the processing table. Under the action of the two second springs, the two sliders are pushed toward each other, so that the clamping frame moves toward each other accordingly. The auxiliary rollers rotatably connected inside the clamping frame contact and clamp the outer wall of the battery body, and the battery body is clamped in the center on the top surface of the processing table. At this time, the operator pushes the ear fixedly installed on the outer wall of the battery body to between the bottom plate and the pressure plate, and the leveling work can be carried out. With the support and assistance of the auxiliary rollers and the conveying rollers, the battery body can be stably conveyed to improve the convenience of the leveling work.
